The total number of marbles in the bag is 8 (red) + 4 (blue) + 3 (green) = 15.
The probability of selecting a red marble is the number of successful outcomes (selecting a red marble) divided by the number of total outcomes (the total number of marbles).
Therefore, the probability of selecting a red marble is 8/15.
The theoretical probability is the same as the calculated probability, which is 8/15.
A bag contains 8 red marbles, 4 blue marbles, and 3 green marbles. If a marble is chosen at random, what is the probability of selecting a red marble?
